GEORGE H. VINING, OF KANSAS CITY, MISSOURI.

CASTING APPARATUS.

To all whom it may concern:

Be it known that I, GEORGE H. VINING, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Casting Ap paratus,of which the following is a specification.

My invention relates to improvements in casting apparatus; and myobjects are first, to provide a furnace and a crucible which latter isadjustable on the former and acts to a certain extent as a damper forregulating the fire in the furnace; second, to provide an adjustabletable for supporting objects, such for instance as journal-bearings,beneath the spout of the crucible so that when the latter is tipped upto pour the molten metal therefrom the same may be properly distributedthroughout the object by moving the table backward or forward; third, toprovide means whereby the cruci ble may be lifted from the furnace andcarried some distance therefrom preparatory to pouring the molten metal.

Other objects of the invention will hereinafter appear and in order thatsaid inven tion may be fully understood, reference will now be made tothe accompanying drawings, in which:

Figure 1 represents a front elevation of the invention. Fig. 2represents a vertical central section on line II-II of Fig. 1. Fig. 3represents a plan view of the invention. Fig. 4 is a front elevation ofa hanger and a portion of the table employed in carrying out theinvention. perspective view of the crucible and a carrier for handlingthe same. Fig. 6 is a broken detail of the upper portion of the furnace.Fig. 7 is a detail perspective of a modified form of carrier.

The furnace consists of a bottom plate 1, a shell 2 resting thereon andopen at its upper end, and a fire-pot 3 dividing the shell into acombustionchamber 4L and an ash-pit 5. The combustion-chamber and theashpit have openings which are normally closed by doors 6 and 7,provided with handles 8 and 9, respectively, whereby they may be openedor closed. Door 6 is slidably mounted in a grooved guide 10 and an eX-tension 11 on the front portion of the firepot. Door 7 is slidablymounted upon the Specification of Letters Patent.

justable on the furnace and adapted to rest v in the upper portionthereof, it being provided with a collar 19, adapted to engage the uppersurface of the furnace, and together with the crucible close the openend of said furnace. The crucible is also provided with a handle 20, ahandhold 20 slidably mounted upon handle 20, a spout 21, and a removableskimmer 22. Spout 21 .eXtends from the upper to the lower portion of thecrucible, and skimmer 22 extends almost to the bottom of the spout,leaving only a small opening 23 through which to pour the molten metalfrom the crucible. By arranging the skimmer in this manner it willintercept the dross arising to the surface of the molten metal so thatit cannot be poured from the crucible therewith and thus producedefective castings.

Spout 21 is provided at its opposite sides with trunnions 24 which aremounted in bearings 17 to support the crucible when it is tipped upwardto pour the metal therefrom. The crucible is also adjusted or tippedupward to allow a column of cold air to pass downward into the furnaceand thus regulate the fire therein. When it is adjusted upward for thispurpose, it is supported by its handle and a ratchet-bar 25 pivot-allymounted upon a bolt 26 engaging the front portion of the furnace.Ratchet-bar 25 is provided with a finger 27 adapted to contactwith thetop of the furnace, and thus limit the pivotal movement of theratchet-bar when the same is thrown to the inoperative position shown inFig. 1.

28 designates a lid secured to the upper rear portion of the furnace bya hinge 29 and provided with a handle 30, so that when desired it may bethrown up to the dotted position shown in Fig. 1, where it is secured byany suitable means, a turn-button 31 be ing shown for this purpose.vided with an extension 28" and a downturned end 28*, adapted to closespout 21 when the lid is resting upon the crucible.

When a fire is started in the furnace, lid 28 is let down upon thecrucible to retain the heat therein, but when the temperature exceeds acertain degree the crucible is adjusted upward as shown in Fig. 2, toallow a column of cold air to descend into the furnace for the purposeof reducing the temperature therein. Lid 28 is in turn raised by thecrucible to admit cold air to the contents of the latter to preventoverheating said contents.

32 designates a hanger consistin of a pair of parallel rods 33 united attheir Iower ends by a transverse bar 34 and bent at their upperterminals to form hooks 35, which removably engage bearings 16.

36 designates a table adjustably mounted on the hanger for the purposeof supporting journal-boxes or other objects beneath the spout of thecrucible. Said table consists of a lower section 37 and an upper section38, which latter is provided wit-h a pair of runners 39 whereby it mayslide back and forth to the positions shown by full and dotted lines,Fig. 3. This movement is desirable because when babbitting a journalboxit permits the latter to be moved back and forth, so that the metal maybe equally distributed throughout the same as it 15 poured from thecrucible. This movement is also advantageous when pouring remelted scrapmetal to form ingots.

The upper section of the table is held upon the lower section by adepending stud-bolt 40, which extends loosely through a longitudinalslot 41 in the lower section, and is secured with a nut 4L2. The lowersection 37 is provided with a pair of depending sleeves 43 whichslidably embrace rods 38 so that the table may be adjusted toward oraway from the crucible spout and thus accommodate castings of differentheights. Ordinarily, the sleeves are sufiicient to support the table andits load, by reason of the fact that the forward end of the table has atendency to drop down a slight distance beyond its rear end and thuscause the sleeves to bind upon the rods, but I also provide one of thesleeves with a set-screw 44: adapted to abut against the adjacent rod33, and thus reliably lock the table from accidental downward movement.

l/Vhen operating on work too heavy to be supported by the table, it isnecessary to remove the crucible from the furnace and carry it to thework, so I provide a carrier d5, consisting of a handle 46 and a pair ofdepending hooks 47, which latter are adapted to engage the trunnions24f, as shown in Fig. 5. The carrier 4t5 and handle 20 afford convenientmeans whereby two or three men Lid 28 is pro- I may transport thecrucible to the work. Hooks 47 are spaced apart so they may engage thetrunnions while the latter are resting in bearings 17, withoutinterfering with said bearings.

\Vhere small crucibles are employed, that can be easily handled by oneman, I provide the modified form of carrier 443 shown by Fig. 7consisting of a handle 46 hooks M and a shank L9 connecting the handleand the hooks.

Having thus described my invention, what I claim is 1. In combination, afurnace open at its upper end, a crucible adjustably mounted on thefurnace and adapted to rest in the upper open end thereof, and a tablesupported by the furnace beneath the spout of said crucible.

2. In combination, a furnace, a crucible adjustably mounted on saidfurnace, adapted to either close or partly open the upper end thereof,and a lid hinged to the furnace and adapted to rest on the crucible sothat it will be lifted to partly open the same when the crucible .isadjusted to partly open the furnace.

3. In combination, a furnace open at its upper end, a crucible adjustably mounted on the furnace and adapted to rest in the upper endthereof, a handle on said crucible for adjusting it up or down, and aratchet-bar secured to the furnace, adapted to be engaged by the handleto support the crucible in any of its adjusted positions.

4. In combination, a furnace, a crucible adjustably mounted on saidfurnace adapted to either close or partly open the upper end thereof, ahandle on said crucible, a ratchet-bar pivoted to the furnace adapted tobe engaged by the handle to support the crucible in any of its adjustedpositions, a lid hinged to the furnace and adapted to rest on thecrucible so .it will be lifted thereby to partly open the same when thecrucible is adjusted to partly open the furnace, and means adjacent thelid for holding the same upward in an inoperative position.

In combination, a furnace open at its upper end, a crucible adjustablyand removably mounted on the furnace adapted to either close or partlyopen the upper end thereof, a lid hinged to the furnace and adapted torest on the crucible, so it will be lifted thereby to partly open thesame when said crucible is adjusted to partly open the furnace, and aturn-button adjacent the lid for holding the same upward in aninoperative position.

6. In combination, a furnace open at its upper end, a crucible adjustably mounted on the furnace adapted to partly close the upper endthereof, a collar surrounding the upper portion of the crucible adaptedto rest on the upper end of the furnace when said crucible is adjustedto its lowermost position, bearings on the upper portion of the furnace,and trunnions projecting from opposite sides of the crucible spoutmounted in said bearings.

7. In combination, a furnace, a crucible adjustably mounted thereon, ahanger depending from the furnace, and a table supported by said hangerbeneath the spout of said crucible.

8. In combination, a furnace, a crucible adjustably mounted thereon, ahanger depending from the furnace, and a table support-ed by said hangerbeneath the spout 01' said crucible, said table being vertically adjustable on the hanger, substantially as described.

9. In combination, a furnace, bearings thereon, a crucible on the upperportion of the furnace provided with trunnions mounted in the bearingsthereon, a hanger removably engaging the bearings, and an adjustabletable supported by thehanger beneath the spout of the crucible.

10. In combination, a furnace, a crucible mounted on the upper portionthereof, and a table supported by the furnace beneath the spout of thecrucible, said table consisting of a lower section and an upper sectionwhich latter is movable on the former, for the purpose described.

11. In combination, a furnace, bearings thereon, a crucible adapted torest in the upper portion of the furnace, trunnions on said cruciblemounted in the bearings on the furnace, and a carrier having hookedterminals adapted to engage the trunnions While the latter are restingin the bearings.
